Pervasive green algae
Hi I have a 100 gallon reef tank and have a pervasive algae problem that has caused a die off. I currently have crabs and snails eating the algae but I think it's too much. Any ideas how I can get rid of it? Lots of tiny air bubbles come off the algae too. Pics attached.
Thanks. |

The one picture also shows a bunch of yellow polyps that have been closed for 3 weeks and haven't opened up.

You should tackle the source of problem at the same time or you will not find anything that will keep up.
Now, my tuxedo urchin is a beast eating algae. Sent from my SM-N950U using Tapatalk

Thanks for the feedback. First thing is from the pictures am I dealing with cyanobacteria or dinoflagellates? I've been treating the tank for cyanobacteria but maybe it's dinos instead. I've also put anti-phosphorous filters in. I've read that dinos are brown but the algae I have appears to be pretty green.
Second question - is there anything I can do to save those yellow polyps? They've been closed up now for 3 weeks and I'm worried they will all soon be dead. |

You've got several kinds of algae but the dominate type looks like hair algae. Start manual removal of the algae along with frequent water changes and get some urchins. If possible take the rock out and using water from the aquarium scrub off the algae in a bucket. Stop removing phosphate once it drops to reef normal levels (.13 mg/l is average).

Fluconazole will rid your tank of hair algae and others. Mechanically remove what you can and get your nutrients under control. Algae is packed with nutrients so your water may test out ok. Mechanical removal is a must to eliminate those nutrients. Fluconazole will kill the algae but it doesn't remove the nutrients so long term you've got to get rid of all the excess nutrients.
